Definitions
- the invention relates to a frame for a cooktop which consists of profile pieces, the profile pieces at least partially encompassing the cooktop and having a visible surface, and wherein a receiving device is connected to the frame and holds electrical installation units arranged under the cooktop.
- Such frames are known from DE 88 01 334 IM. Such a frame is used, for example, to create a transition between a ceramic hob and a subsequent worktop.
- the frame primarily takes on the task of fixing the hob and achieving an optical conclusion. To define, include - 2 -
- the profile pieces are usually connected in one piece to form a closed frame. However, it is also conceivable to provide individual profile pieces which are then connected to one another.
- the visible surface projects beyond the edge areas of the hob and the worktop, as well as the gap between the hob and worktop.
- the plastic from which the frame is made is colored or the visible surface is painted in the case of high-quality frames.
- the disadvantage of the paint is that it is easily scratched when pots are pulled over the frame.
- graphically designed decorations cannot be applied with reasonable effort.
- the object of the invention is achieved in that the visible surface is covered with a film.
- the film Since the film is applied to the frame as a separate part, the physical properties of the visible surface can also be changed.
- the film can be scratch-resistant and pressure-resistant. It is also advantageous if the film is resistant to chemicals.
- the frames can be manufactured in very small batch sizes, since each frame can be individually covered with a film.
- the profile pieces are combined in one piece, that the profile pieces and / or the film consist of a thermosetting plastic material, the plastic material for the profile pieces being uncolored. Since the visible surface alone is facing the viewer, there is no need to color the plastic.
- the thermosetting plastic will mainly consist of melamine and can be glass fiber reinforced. When using different materials, different material properties can also be used, so that the frame can be individually adapted.
- the frame can be manufactured in one operation.
- the plastic material can be cut to length from a semi-finished product, for example.
- the plastic material is brought into a deformable state.
- the frame is shaped.
- the film is pressed onto the visible surface and intimately connected to it due to the supply of heat. It has proven to be advantageous if it is provided that the dimensions of the film are cut so that it laterally projects beyond the visible surface after the thermal pressing, and that after the thermal pressing the protruding parts are cut off when the frame is deburred become.
- the film is dimensioned larger than the visible surface, the rejects are reduced to a minimum, since even when the film is displaced with respect to the frame during the pressing process, complete coverage of the visible surface is always guaranteed. Furthermore, the fact that the protruding parts are finally separated off creates a defined closure with the visible surface.
- the film is placed on the visible surface of the frame made of plastic and connected to it with the supply of heat.
- the frame is a prefabricated part that is manufactured, for example, by injection molding. This can then be coated with the film afterwards.
- Fig. 1 is a perspective view of a ceramic hob and a frame and
- a ceramic cooking field 10 is shown, which is surrounded by a frame 20.
- the frame 20 consists of individual profile pieces which are connected to one another in one piece.
- the profile pieces have a vertical web 22 to which a plate is connected at right angles.
- the plate forms a visible surface 21 which faces upwards.
- Plate and web 22 are assembled in a T-shaped cross section.
- the visible surface 21 is flat in the present case.
- any other surface profile is also conceivable.
- a wave profile or spikes can be provided.
- a film 40 is applied to the visible surface 21 itself.
- a receptacle for electrical installation elements can be connected to the web 22.
- fastening options are available on the web 22, for example.
- the receiving device is integrally connected to the frame 20.
- a pressing tool which consists of a first and a second mold half 31 and 32.
- the first mold half 31 has a stamp 35, into which a receptacle 33 is inserted.
- the receptacle 33 forms the negative contour of the frame 20.
- a recess 34 is made in the second mold half 32. The punch 35 of the first mold half can be inserted into this.
- the film 40 is first inserted into the recess 34 of the second mold half 32 with the pressing tool open. placed.
- the side of the film 40 which has, for example, the decor, the surface structure, etc., faces in the direction remote from the stamp 35.
- a plastic material 23 is cut and inserted into the second mold half 32 above the film 40.
- the recess 34 is widened upwards.
- Plastic material 23 and film 40 are thus supported on a shoulder and are arranged at a distance from the bottom surface of the recess 34.
- the pressing tool is closed.
- the first mold half 31 is moved onto the second 32.
- the punch 35 penetrates into the recess 34.
- the plastic material is brought into a deformable state with the supply of heat, so that it flows into the receptacle 33 when the pressing tool is closed.
- the web 22 of the frame 20 is thus formed.
- the plate which carries the visible surface 21 is formed between the end face of the punch 35 and the second mold half 32.
- the film 40 is simultaneously drawn further into the recess 34 and lies over the resulting visible surface 21 of the frame.
- the pressing tool When the pressing tool is closed, the entire negative frame contour is filled with the plastic material 23 and the film 40. This creates a pressure in the press tool. As a result of this pressure and the heat supplied, the film 40 and the visible surface 21 of the frame 20 connect to one another. After a dwell time, the frame 20 hardens. Then the pressing tool can be opened again and the frame 20 can be ejected, as shown in FIG. 2d. As can be seen from this illustration, the film 40 was in its raw state dimensioned larger than the visible surface 21 of the frame 20, so that pieces of waste project beyond the visible surface 21. These protruding parts are separated in a final deburring step. This situation is shown in 2c.
- the frame 20 is inserted with its visible surface 21 facing downward in a recess 61 of a receiving part 60.
- the web 22 protrudes over the receiving part 60.
- the protruding pieces of the film 40 are then cut off with a tool 50 and at the same time the plate carrying the visible surface 21 is deburred. Because the protruding parts are separated and the deburring takes place at the same time, the film 40 can always be flush with the visible surface 21.
